Question

a piece of a wire is in the shape of rectangle whose length and breadth are 50 cm and 38 represent it is rebent in the form of a circle find the radius of the circle. (Please step by step)

Answer 1

Answer: 302.55 (approximate)

Step-by-step explanation:

The same rectangular wire is rebent in the form of the circle.

So, the perimeter of the rectangle is equal to the circumference of the circle.

Perimeter of rectangle = circumference of the circle

l × b = 2πr

50 × 38 = 2 × 3.14 × r

1900 = 2 × 3.14 × r

1900/2 = 3.14 × r

950 = 3.14 × r

950= 3.14 r

950/3.14 = r

95000/314 = r

302.55 = r

The radius of the circle formed by rebenting the wire is 302.55 cm.
